Solar Panel Cleaning

Window Hygienics provides professional solar panel cleaning in San Diego for residential and commercial properties. We safely remove dust, dirt, pollen, bird droppings, and buildup that reduce solar efficiency—helping your system produce more energy and perform at its best.

If your panels look dirty, your energy output is already being affected. Our specialized cleaning process restores clarity and maximizes performance without causing damage.

Maximize Solar Efficiency with Professional Cleaning

San Diego’s dry climate, coastal air, and dust-heavy conditions cause rapid buildup on solar panels. Even a light layer of dirt can significantly reduce energy production.

Our solar panel cleaning service helps:

• Improve energy output and system efficiency
• Extend the lifespan of your solar panels
• Prevent long-term buildup and staining
• Maintain optimal performance year-round

Safe, Spot-Free Solar Panel Cleaning Process

We use a professional pure water system (reverse osmosis and deionization) combined with a rotary brush cleaning system to safely and effectively remove buildup from your solar panels—without harsh chemicals or abrasive methods.

Our process:

• Uses purified, spot-free water for a streak-free finish
• Utilizes a rotary brush system to gently agitate and lift dirt, dust, and debris
• Breaks down stubborn buildup like pollen, bird droppings, and residue
• Protects panel coatings and surfaces from damage
• Reaches roof-mounted systems safely and efficiently
